Workflow Error for no reason

Does anybody have any idea why the workflow would keep crashing here:

1230×1034 121 KB

My “Change that shit into an array” function node is working correctly (Has been for months) but sometimes out of the blue n8n keeps erroring on that specific node, It does have valid data, It simply fails to move on to the next nodes

Incase anybody wonders what the function node contains:

const newItems = [];
for (const item of items[0].json) {
  newItems.push({json: item});
}
return newItems;

Really simple default code

So out of the 1440 times the workflow is executed each day, It would fail ~5 times
Sometimes once, sometimes 6 times, It’s always random

These are the last few error lines in my n8n log:

Sounds like your server may run out of memory. Could that be the problem?

Hmm, It has 16GB’s and while running n8n it never goes above 60%
Utilisation is about 6.7GB out of 15.5GB
